Fig. 2: zeigt beispielhaft eine Feldbusanordnung.2 shows by way of example a fieldbus arrangement.
Fig. 3: zeigt eine Diagnose-Einrichtung für einen Feldbus, wie sie bereits als Stand der Technik bekannt ist. Fig. 3: shows a diagnostic device for a Fieldbus, as already known as the prior art is.
In FIG. 1 ist die erfindungsgemäße Anordnung einer
Diagnose-Einrichtung mit einer Diagnose-Vorrichtung 11
für einen Feldbus dargestellt. Die feldbusspezifischen
Diagnose-Informationen sind in der Feldbus-Anschaltbaugruppe
4 für die Weiterverarbeitung in der
Diagnose-Vorrichtung 11 abgespeichert. Die Feldbus-Anschaltbaugruppe
4 ist mit seiner I/O-Schnittstelle 8 an
den in der SPS 1 befindlichen SPS-I/O Bus 6 angekoppelt,
so daß die Feldbus-Anschaltbaugruppe 4 in gleicher Weise
von der Steuerungs-Anwendung 3 angesprochen werden kann,
wie die I/O-Einheiten 5. Häufig ist an der SPS 1 eine
Anzeigevorrichtung 10 angeschlossen, welche eine zur
Steuerungs-Anwendung 3 zugehörige
Visualisierungsanwendung 13 enthält. Über die
Datenverbindung 18 zwischen der externen Schnittstelle
der SPS 7 und der externen Schnittstelle des PCs 17
werden alle notwendigen Informationen übertragen. Als
zusätzliche Komponente wird die Diagnose-Vorrichtung 11
in der Anzeigevorrichtung 10 aktiviert, die die Feldbus
betreffenden Diagnose-Informationen zur
Weiterverarbeitung oder zur anzeigenden Ausgabe erhält.
Damit die Übermittlung der Diagnose-Informationen von der
Feldbus-Anschaltbaugruppe 4 zur Diagnose-Vorrichtung 11
ohne Anpassung oder Programmierung der
Steuerungsanwendung oder Visualisierungsanwendung
erfolgen kann, sorgen Interfaces 2, 12 für die
entsprechende Datenzuordnung. Über die
Softwareschnittstelle 28 erfolgt die Bedienung der
Diagnose-Vorrichtung 11 aus der Visualisierungsanwendung
heraus, Rückmeldungen aus der Diagnose-Vorrichtung 11
erfolgen ebenfalls über diese Softwareschnittstelle 28
zur Visualisierungsanwendung 10. In FIG. 1 shows the arrangement according to the invention of a diagnostic device with a
Im folgenden wird die Übermittlung der Diagnose-Informationen
von der Feldbus-Anschaltbaugruppe 4 zur
Diagnose-Vorrichtung 11 beschrieben. Die in der Feldbus-Anschaltbaugruppe
4 vorgehaltenen den Feldbus
betreffenden Diagnose-Informationen werden über den SPS-I/O-Bus
6 zu dem Interface in der SPS 2 übertragen. Die
Verbindung 14 für die Diagnose-Informationen zwischen der
Feldbus-Anschaltbaugruppe 4 und dem SPS-I/O-Bus 6 ist für
den SPS-I/O-Bus 6 angepasst und kann auch ausschließlich
logischen Charakter haben. Über den SPS-I/O-Bus 6 werden
sowohl I/O-Daten als auch Diagnose-Informationen für den
Feldbus zum Interface in der SPS 2 übertragen. Das
Interface in der SPS 2 schaltet die logischen
Verbindungen. Die Diagnose-Informationen werden zur
externen Schnittstelle der SPS 7 geleitet. Die I/O-Daten
werden über die interne logische Verbindung 25 zur
Steuerungs-Anwendung 3 geleitet.
Visualisierungsinformationen gelangen aus der Steuerungs-Anwendung
3 über die interne logische Verbindung 16 zum
Interface der SPS 2, welches diese zur externen
Schnittstelle 7 der SPS 1 leitet. Die externe
Schnittstelle 7 der SPS 1 kann eine V24-Schnittstelle
oder eine Ethernet-Schnittstelle oder eine Schnittstelle
für ein andere Übertragungsart, wie Parallelübertragung
sein.
In der Anzeigevorrichtung 10 mit der Visualisierungsanwendung
13 werden die über die externe Schnittstelle 17
im PC 10 Visualisierungsinformationen und Diagnose-Informationen
für den Feldbus empfangen. Das Interface 12
im PC 10 lenkt die empfangenen Informationen ihrer
Zugehörigkeit entsprechend entweder an die
Visualisierungsanwendung 13 oder an die Diagnose-Vorrichtung
11 weiter. Visualisierungs-Informationen
werden zur Visualisierungsanwendung 13 geleitet,
Diagnose-Informationen werden über den internen logischen
Kanal 15 zur Diagnose-Vorrichtung 11 geleitet. Die
Visualisierungsanwendung 13 wird dabei in seiner
funktionalen Eigenschaft nicht beeinflusst. Das Schalten
aller logischen Verbindungen geschieht in umgekehrter
Richtung ebenfalls, so dass aus der Diagnose-Vorrichtung
11 an die Feldbus-Anschaltbaugruppe 4 Befehle und
Parameter über die Datenverbindung 18 und dem SPS-I/O-Bus
6 übertragen werden können. Aus der
Visualisierungsanwendung 13 können Parameter oder
Programme für die Steuerungs-Anwendung 3 zur SPS 1 über
die Datenverbindung 18 übertragen werden.
Selbstverständlich kann die Anwendung 13 auf dem PC auch
eine Programmieranwendung für die SPS oder eine
Konfigurationsanwendung oder Programmieranwendung für den
Feldbus sein. Das Interface 12 im PC 10 kann aus einer
Software-programmierbaren Datenverarbeitungseinheit oder
aus einer in Hardware ausgeführten Komponente bestehen.In the following, the transmission of the diagnostic information from the field bus interface module 4 to the
In the
In Fig. 2 ist beispielhaft ein an der Feldbus-Anschaltbaugruppe
4 angeschlossener Feldbus 27
dargestellt. Hierbei handelt es sich beispielsweise um
ein INTERBUS-System, wobei es jedoch auch um ein anderes
Feldbussystem handeln kann. Typischerweise enthält der
Feldbus 27 Busleitungen 21 und daran angeschlossene
Module 23, 25, 26, welche Peripheriebeschaltungen
aufweisen als Verbindung zu Sensoren oder Aktoren oder
sonstigen Einrichtungen der Automatisierungstechnik. Eine
Busklemme 22 ist nur beispielhaft für das INTERBUS-System
zur Ankopplung mehrerer Busmodule 23 als funktionale
Gruppierung dargestellt. Eine Störung 24 auf der
Verbindungsleitung vor dem Modul 26 erzeugt einen Fehler,
der in der Feldbus-Anschaltbaugruppe 4 mit möglichst weit
umfassendem Informationsgehalt (Fehlerart, -dauer, -ort,
usw.) gespeichert wird. FIG. 2 shows by way of example a
In Fig. 3 ist eine Diagnose-Vorrichtung 21 dargestellt,
wie es nach bekannter Art und Weise seine Diagnose-Informationen
erhält. Eine eigens hierfür vorgesehene
physikalische Verbindung 19 transportiert die Diagnose-Informationen
zur Diagnose-Vorrichtung 11. In umgekehrter
Richtung können aus der Diagnose-Vorrichtung 11 an die
Feldbus-Anschaltbaugruppe 4 Befehle und Parameter zum
Busbetrieb gesendet werden. Der SPS.I/O-Bus 6 enthält nur
I/O-Daten, so daß die Steuerungsanwendung 3 diese Daten
direkt erhalten kann. Über die Datenverbindung 20
zwischen den Schnittstellen 7 und 17 werden von der
Steuerungsanwendung 3 nur Visualisierungsinformationen
oder sonstige steuerungsspezifische Daten übertragen und
in umgekehrter Richtung werden von der
Visualisierungsanwendung 13 nur steuerungsspezifische
Parameter oder Programme für die Steuerungsanwendung 3
übertragen.In Fig. 3 , a
